VM29 S/Bore Jetting?

renobruce said:
Where did you find your cam cover bolts? Are those chrome flange heads?
Click to expand...

Yes they are. They are Suzuki's new style cam cover bolts and I personally like the flange better than the original bolt head style.

Man that's a sweet looking setup. It's a shame that you have to ride it and get it all dirty!

One other thing, how are you going to fit up your airbox with all that new plumbing around those carbs? :p

Enjoy your new mods.

49er, I get those clean comments a lot. I cannot help it. ;) I wish I could post the original Polaroids (sic) of this thing with the Shoei FM-2 fairing & highway bars!
 
Have you got this quiet shinny thing correctly jetted and running yet? Or has winter slowed your enthusiasim/progress?

The answer is yes but you side tracked me on that cam end float modification. Like so many other threads I never crossed the T's & dotted the I's. So this VM29 setup works seamlessly on my GS1000/1085 at altitude 5150 feet.

Mikuni VM29 S/B Configuration (12/05/08)
Pilot: 22.5
Needle: 5DL31-4
Main: 127.5
Air Screw: 1/2 - 1 turn out
Throttle Valve Cut Away: 2.0

79 GS1000: Wiseco 1085 10.25cr
Andrews S-1 & H/D valve springs
Dyna 3 Ohm Coils, Dyna III Ignition & Accel wires
Falicon welded & balanced clutch basket
K&N Pods
Supertrapp 4into1 w 20 discs

Notes:
1) Most VM29 were equipped with 1.5 T/V Cuts and it's suprising how close my setup is to Sudco's 2.0 T/V recommendation.

2) To get that accurate main jet reading, mark your kill switch & throttle with alignement marks of your choice that positively indicate 3/4 opening. Be careful out there because even in 4th gear you will quickly find that needle is swinging way past 100 mph.

Thanks for the set-up info!! I'm at 5210 ft. with basically the same mods on my project. :D The only difference I see is that my head is ported and I will have different cams. Where are your needle clips?

I have got the needle clips set at #4 with the following needle orientation: #1 is at the top & #5 is closest to the tip. Hope that helps.

I just started dipping my set. Looks like I have the "Kawasaki" set-up:

Pilot: 25
Needle: 5DL31
Main: 120
Throttle Valve Cut Away: 1.5

Without going through this whole thread, didn't you mention somewhere that you started out with the 1.5 cut aways?
 
Geez, I like a happy ending. :) Should be in the ball park for you too Bruce.

I'm hoping I can make my set work with the 1.5 cut aways. They want over 50.00 each for new ones! :eek:

That's why I replated a used set of 2.0 T/V with Electroless Nickel. All other things being equal the 1.5's can be considered richer than the 2.0's. The 1.5 work fine at sealevel as many owners & myself can attest to. But when I moved to Denver I could not eliminate a part throttle stumble when transitioning between the pilot & needle which occurred right @ 3000 rpm. The 2.0's fixed that symptom on mine. I would just run it and see if you even have a problem before throwing money at like I have done stupidly over the years.

I did see a nice set of VM29 slides on EBay 3 weeks ago which I watched for curosity sake. Starting bid $100 for the set, no bids.

Good luck
 
As you can see on these pages http://www.sudco.com/vol33/33-36.pdf the Kaws and Suzukis used different slides on the smoothbore carbs. I bought a new set (many years ago) of 33 smoothbores for a friends KZ1000 and it ran poorly after endless jetting. Turns out they sent us a set for a Suzuki.....Instead of returning the carbs, they just sent me the correct slides, air jets , etc. and the bike ran great......Billy

Thanks for the link BBB. I see that many of the parts that are still available for the 29's have the VM26 prefix, including the fuel tees and o rings which some have said were no longer available for the VM26SS.
Also the slides go up to 2.5 cutaway. They dont list the matching jetting for either Kawa or Suzi models. Must be for those running over 10,000 ft above sea level, eh? :p
 
Do you recall what your set-up was when you lived at sea level? I'm rebuilding a set of 29's for Tom MLC, and he lives at sea level. His GS1000 is stock except for pipe and pods. His set of 29's have the 1.5 tv's. like you originally had. Thanks.
 
hmm i might be able to help when i get home, i can dig into my carbs and see what's inside, I have the 1.5 slides too. I got everything running pretty good when i was living in chicago and the bike was stock, not sure what elevation that is compared to Tom. I think the only thing i changed was I went a little smaller on the piliots.
 
ok i just check, i am running 1.5 cut aways, 117.5 mains and #20 piliot jets. It was running good in chicago and robinsville north carolina. I would try that and see how it goes. This was a stock engine with pods and a 4 into 1.

Thanks, Ryan! A big help. Did you notice where the needle clips were?
 
Hey Bruce, you KNOW polishing & cylinder boring are an EFFECTIVE means of weight reduction?!!! LOL!! Ray.
